The scald guard that comes with your Delta shower system helps prevent you from getting burned by water, but it can also keep your water from being warm enough.
Delta’s scald guard was designed for convenience, allowing you to adjust the water temperature without accessing your water heater or turning off your water supply. Each Delta faucet model comes with its own way of adjusting the scald guard. It’s vital you determine which model you have and follow the instructions for that specific model.
It can be easy to mix up the scald guard instructions for one Delta series with another. So it’s important to know the differences between each.
You don’t have to put up with a lukewarm shower experience. Learn how to adjust your Delta scald guard and get the hot shower you deserve.

How to Identify a Delta Shower Faucet Model
There are a few ways to identify your Delta faucets series or model number.
First, if you kept the instruction or user’s manual that came with your faucet, the model number should be right on the cover or on the first few pages.
Delta’s website also has a product identifier tool in which you can enter a description of the faucet to possibly get a model number.
Unfortunately, the product identifier tool will only work for newer delta products that have been released in the last five years.
Lastly, you can check the faucet’s model number by taking it apart. Whether you have a scald guard or scald-proof faucet, the type of handle and the showerhead can all help you narrow down the possibilities and figure out which model you have.
In addition, some models have numbers imprinted on them which can point you in the right direction.
